The answer varies widely as the no of repeating units is not a constant.. the ans can range anywhere inbetween 4500 to 11500.
it is the molar mass of one (86g/mol) multiplied by 1517 which is 130462 g/mol
To find the number of moles in 20.67g of sodium chloride, you need to first calculate the molar mass of NaCl (sodium chloride), which is approximately 58.44 g/mol. Then, divide the given mass by the molar mass to get the number of moles. In this case, 20.67g divided by 58.44 g/mol is approximately 0.354 moles of sodium chloride.
Need to know the mass of BaCl2 in order to calculate molarity.
No, KCI (potassium chloride) has a molar mass of approximately 74.55 g/mol.
To find the number of moles in 55g of lithium chloride, we first need to calculate the molar mass of lithium chloride, which is approximately 42.39 g/mol. Then, we divide the mass given (55g) by the molar mass to get moles. Therefore, 55g of lithium chloride is approximately 1.30 moles.
it is the molar mass of one (86g/mol) multiplied by 1517 which is 130462 g/mol
The molar mass of sodium chloride is 58,44.
To calculate the milliequivalents of chloride ions in 0.725 grams of chloride, you first need to determine the molar mass of chloride (Cl⁻) which is 35.45 g/mol. Next, calculate the number of moles in 0.725 grams by dividing the mass by the molar mass. Then, convert moles to milliequivalents by multiplying by 1000 (since 1 mole of ions = 1000 milliequivalents).
To make a 3 Molar solution of potassium chloride in 250 milliliters: Calculate the mass of potassium chloride needed using its molar mass. Dissolve this mass of potassium chloride in a small amount of water, then add water to bring the total volume to 250 ml. Stir to ensure complete mixing and dissolve the potassium chloride completely.
To calculate the mass of sodium chloride produced, first balance the chemical equation for the reaction between sodium oxide and calcium chloride. Next, determine the molar ratio between sodium oxide and sodium chloride in the balanced equation. Finally, use the given mass of sodium oxide and the molar mass of sodium chloride to calculate the mass of sodium chloride produced.
The molar mass of anhydrous aluminum chloride is 133,34 grams.
To calculate the molar heat of solution of zinc chloride, we use the heat evolved by dissolving 1 gram of ZnCl2 in water. First, we convert the mass of ZnCl2 to moles using its molar mass of 136.3 g/mol. Then, we divide the heat evolved by the number of moles dissolved to get the molar heat of solution. In this case, the molar heat of solution would be 3.89 kJ/mol.
To calculate the number of moles of potassium chloride in a 100.0g sample, you need to divide the mass of the sample by the molar mass of potassium chloride. The molar mass of potassium chloride is approximately 74.55 g/mol. Therefore, 100.0g ÷ 74.55 g/mol = approximately 1.34 moles of potassium chloride in the sample.
To calculate the number of moles of aluminum chloride in the test tube, you need to know the molar mass of aluminum chloride (AlCl3). The molar mass of AlCl3 is 133.34 g/mol. Given that you have 2.0 ml of AlCl3, you will need to convert this volume to grams using the density of AlCl3. Finally, you can calculate the moles using the molar mass.
To find the mass of zinc chloride (ZnCl2) in 0.0435 mol, you need to calculate the molar mass of ZnCl2, which is 65.38 g/mol. Multiplying 0.0435 mol by the molar mass gives a mass of approximately 2.84 g.
you mean to say chlorine... and it 35.45g/mol
The molar mass of aluminum chloride (AlCl3) is approximately 133.34 g/mol.
